Watched this in Spanish with English subtitles (annoyingly on Hulu you have to search for "largas sombras" and not "past lies" to get the non-dubbed version). Reminded me a lot of Yellowjackets mixed with Big Little Lies, with its female-focused cast, complex relationships, flashbacks to the past, and whodunit style. Would recommend if you liked those two shows, and/or Bad Sisters!
